Abstract
Variability in coral hosts susceptibility to Vibrio coralliilyticus is well-documented; however, the comprehensive understanding of tolerance of response to pathogen among coral species is lacked. Herein, we investigated the microbial communities and transcriptome dynamics of two corals in response to Vibrio coralliilyticus. Favites halicora displayed greater resistance to Vibrio coralliilyticus challenge than Pocillopora damicornis. Furthermore, the relative abundances of Flavobacteriaceae, Vibrionacea, Rhodobacteraceae, and Roseobacteraceae increased significantly in Favites halicora following pathogen stress, whereas that of Akkermansiaceae increased significantly in Pocillopora damicornis, leading to bacterial community imbalance. In contrast to the previous results, pathogen infection did not have much effect on the community structures of Symbiodiniaceae and fungi, but led to a decrease in the density of Symbiodiniaceae. Transcriptome analysis indicated that Vibrio infection triggered a coral immune response, resulting in higher expression of immune-related genes, which appeared to have higher transcriptional plasticity in Favites halicora than in Pocillopora damicornis. Specifically, the upregulated genes of Favites halicora were predominantly involved in the apoptosis pathway, whereas Pocillopora damicornis were significantly enriched in the nucleotide excision repair and base excision repair pathways. These findings suggest that coral holobionts activate different mechanisms across species in response to pathogens through shifts in microbial communities and transcriptomes, which provides novel insight into assessing the future coral assemblages suffering from disease outbreaks.

Abstract
Microbial life is at the heart of many diverse environments and regulates most natural processes, from the functioning of animal organs to the cycling of global carbon. Yet, the study of microbial ecology is often limited by challenges in visualizing microbial processes and replicating the environmental conditions under which they unfold. Microfluidics operates at the characteristic scale at which microorganisms live and perform their functions, thus allowing for the observation and quantification of behaviors such as growth, motility, and responses to external cues, often with greater detail than classical techniques. By enabling a high degree of control in space and time of environmental conditions such as nutrient gradients, pH levels, and fluid flow patterns, microfluidics further provides the opportunity to study microbial processes in conditions that mimic the natural settings harboring microbial life. In this review, we describe how recent applications of microfluidic systems to microbial ecology have enriched our understanding of microbial life and microbial communities. We highlight discoveries enabled by microfluidic approaches ranging from single-cell behaviors to the functioning of multi-cellular communities, and we indicate potential future opportunities to use microfluidics to further advance our understanding of microbial processes and their implications.

Coral thermal stress and bleaching enrich and restructure reef microbial communities via altered organic matter exudation. Commun Biol 2024; 7:160.

Abstract
Coral bleaching is a well-documented and increasingly widespread phenomenon in reefs across the globe, yet there has been relatively little research on the implications for reef water column microbiology and biogeochemistry. A mesocosm heating experiment and bottle incubation compared how unbleached and bleached corals alter dissolved organic matter (DOM) exudation in response to thermal stress and subsequent effects on microbial growth and community structure in the water column. Thermal stress of healthy corals tripled DOM flux relative to ambient corals. DOM exudates from stressed corals (heated and/or previously bleached) were compositionally distinct from healthy corals and significantly increased growth of bacterioplankton, enriching copiotrophs and putative pathogens. Together these results demonstrate how the impacts of both short-term thermal stress and long-term bleaching may extend into the water column, with altered coral DOM exudation driving microbial feedbacks that influence how coral reefs respond to and recover from mass bleaching events.

Ecology of Endozoicomonadaceae in three coral genera across the Pacific Ocean. Nat Commun 2023; 14:3037.

Abstract
Health and resilience of the coral holobiont depend on diverse bacterial communities often dominated by key marine symbionts of the Endozoicomonadaceae family. The factors controlling their distribution and their functional diversity remain, however, poorly known. Here, we study the ecology of Endozoicomonadaceae at an ocean basin-scale by sampling specimens from three coral genera (Pocillopora, Porites, Millepora) on 99 reefs from 32 islands across the Pacific Ocean. The analysis of 2447 metabarcoding and 270 metagenomic samples reveals that each coral genus harbored a distinct new species of Endozoicomonadaceae. These species are composed of nine lineages that have distinct biogeographic patterns. The most common one, found in Pocillopora, appears to be a globally distributed symbiont with distinct metabolic capabilities, including the synthesis of amino acids and vitamins not produced by the host. The other lineages are structured partly by the host genetic lineage in Pocillopora and mainly by the geographic location in Porites. Millepora is more rarely associated to Endozoicomonadaceae. Our results show that different coral genera exhibit distinct strategies of host-Endozoicomonadaceae associations that are defined at the bacteria lineage level.
